Question: You have promised 5th version release a few years ago!
Answer:
You have promised 5th version release a few years ago and promised a free upgrade! Have you deceived us?
We really detained 5th version for some reason. Nevertheless, many features have been added in 4th version (64-bit compilation, full Unicode support, etc.). Our customers were obtained these updates free of charge.
